It should, of course, be understood that the description and drawings herein are illustrative merely, and that various modifications and changes may be made in the structure disclosed without departing from the spirit of the invention.

Like numerals refer to like parts throughout the several views.

Referring now more particularly to the drawings, in accordance with the present invention the lamp shade has a frame preferably of wire, and of any suitable conguration for the shape desired. The frame preferably includes a top vertically at horizontal metal ring 20 and a lower vertically at horizontal metal ring 21 held in parallel spaced relation by a plurality of upright metal ribs 22. The ribs 22 may be of a straight or curved configuration and disposed in either an inclined or vertical manner as determined by the shape of the finished shade desired. A spider (not shown) is provided in the conventional manner in fixed engagement with the top ring 20 for facilitating and effecting the support of the lamp shade.

A flat tape 23, of suitable textile material or heavy paper, is provided spirally wound perimetrically about the ring 20 and held in engagement therewith in any suitable manner. The tape 23 may be wound so that there may be provided either one or more layers of the tape 23 on the ring 2li as desired, one layer being preferable. A similar tape 24 is provided for the ring 21.

The lampshade of the present invention has, enclosing the metal frame, an outside layer or covering 25, preferably of suitable textile material, such as silk or the like, and an inside layer or liner 26 of suitable material. The vertical terminal edges of the layer 25 are sewed together vertically to impart the layer 25 a substantially hollow tubular configuration. The layer 26 is similarly formed.

The order of application of the layers 25 and 26 to the frame is not material and either layer 25 or 26 may be applied rst. For the purposes of description the outside layer 25 will be considered as applied first. It is likewise not material whether the layers 25 and 26 are rst secured at the top or bottom of the frame, initial top securing providing somewhat greater facility in obtaining the desired tautness of the covering material. The approach from the top of the frame will be considered for the purposes of explanation.

Referring more particularly to Fig. 2, the layer 25 is positioned with its upper portion on the frame extending for a short distance above the upper or outer edge face of the ring 29 so that a horizontal row of sewing machine stitches 27 may be applied passing through one portion of the layer 25 at the topmost portion thereof as well as the tape 23. The row of stitches 27 is applied just above the top edge face of the ring 20 so that that face of the ring Ztl may act as a guide for the needle of the sewing machine used to apply the row of stitches 27. The layer 25 is pulled downwardly to obtain the desired degree of smoothness and tautness and the lower portion thereof fastened to the bottom of the frame by a row of machine applied stitches 28, as shown in Fig. 3, in a manner similar to that employed for securing the upper portion of the layer 25. At the lower portion of the layer 25, the row of stitches 28 is applied just below the bottommost edge face of the ring 21 and that face is used as a guide for the needle in a manner similar to that previously described. The row of stitches 28 secures the lower portion of the layer 25 to the ring 21 by passing through the tape 24 which is 3. in -fixed lencompassing Aengagement with Ythe ring 21 in a manner similar to the tape 125 on the ring 20.

Referring now to Fig. 5, the inside layer 26 is applied to lthe frame by positioning the upper portion thereo'f over the interior of the ring 2S in Voverlapping arrangement so thattheupper portion ofthe layer 25 is covered by the upper portion of the layer 26 to a point below -the row of stitches 27. A horizontal row of machine stitches 29 is applied at the same location as the stitches 27 thus securing the upper portion of the layer 26 vto Ythe layer 25 and the tape 23. As in previous sewing operations, the topmost edge face of the ring 20 is -use'd Vas a needle guide. The stitches29 pass through two thicknesses of the upper portion of the 'layer '26, 'one thickness on the inner side of the ring 20 and the second thickness on the outer side of the ring 213. The layer 26 is then pulled Vdownwardly to obtain the desired degree of smoothness and tautness and at the lower portion "thereof, as shown in Fig. 6 is brought into overlapping relation Vwith the 'outer edge face of the ring 21 and the 4contiguous stitched portion of the cover layer 25. A horizontal row of stitches 30 is applied, at the same location as the stitches 23, passing through the lower portion 'of the layer 25, the tape 24 and two thicknesses of the Ilower portion of the layer 26 to secure the layer 26 Vin place. The bottommost edge face of the ring 21 serves as a needle guide during the machine sewing operation.

A trimming strip or band 31 is provided at the upper portion of the frame and is secured to the ring 20 on the inner side thereof by a horizontal row of machine stitches 32 which passes through one thickness of the strip 31. The row of stitches 32 is applied at the same location as the rows of stitches 27 and 29, and vusing the topmost edge Vface of the ring 29 as a guide for .the sewing needle. The stitches 32 pass Ythrough the layers 25 and 26 land the tape 23, as shown in Fig. 8, to se-l cure the strip 31 in position. The strip 31 is secured on the inner part only of the ring 2) by the stitches 32 and is then folded over the Vtop and outer edge of the ring 20, being -he'ld in place by the tension applied thereto 'by the folding. In similar manner, a trimming -strip or band 33 is provided secured in position by a horizontal row of stitches 34, which lengages the tape 24 on the ring 21. The strip 33 is secured by the ystitches 34 and is then vfolded under the bottom and outer edge face of the ring 21, Vbeing held in place by tension applied 'thereto 'by the folding. Like the stitches 32, the stitches 34 -pass through the layers 25 `and 26 and the tape -24 as shown 'in Fig. 9 to secure the strip 33 in ,position.

4'It has been previously stated that the order of .application of the layers 25 and 26 :may be selected as desired. .In Figs l to v9, inclusive, the application of the outer layer 25 first is shown; in Figs. 10 to l5, inelusive, the application -of the new inner layer 26 first is shown. Referring t'o Fig. l0, the Vupper portion `of the layer 26 is ypositioned on fthe frame and'secured to the `upper edge face of the ring 2% by a horizontal row ofsewing machine stitches passing through the layer 26 `and 'the tape 23. As previously described the topmost face of the ring 20 is Vused as a needle guide. The lower portion -of the layer -26 is pulled downwardly to obtainva smooth and taut surface thereon and is then secured, in a similar manner, as shown in Fig.V lll, to the tape v24 of the -ring 21 by a horizontal `row of stitches 51 using vthe 'bottommost face of the ring V21 as a needle guide. The outer layer 25 is secured to the tapes V23 and 24 on-therings l2) and y21 in a manner `similar 'fto that used in applying the layer 26 previously, yby horizontal rows of stitches 52 and -53 respectively, as shown in Figs. 'l2 and 13. Similarly, the trimming strips 31 and-33 are secured as before by rows of stitches Swami-55, as shown in Pigs. 14 and l5.

ilf "desired, in ithe manufacture of lamp shades of the character herein disclosed, the layers 25 and 26 may be secured along marginal edges thereof, in any suitable manner such as by a line of stitching 60, before applying to the frame. After the layers 25 and 26 have been fastened together they are positioned on either side of and superposed on the ring 20 as shown in Fig. 16. The lower portions of the layers 25 and 26 may be secured as before with the order of application immaterial, except that the lirst applied-layer is preferably somewhat shorter than the later-applied layer and therefore the order of application of the layers 25 and 26 should be determined beforehand so that the desired length of material is available. Otherwise, both of the layers 25 and 26 would have to be provided at the longer dimension and the first-applied layer preferably trimmed off to meet the desired dimensional requirement. cess of the first-applied layer, but such would be preferable in order to avoida lumpy condition at that 10-V cation. Tne trimming strip `31 as shown in Fig. 17, is then applied as previously described. Similarly, the trimming strip 33 is applied as before.
